Single Triode Regenerative Radio Receiver

This radio employs the most popular and successful regenerative radio circuit used by radio experimenters in the 1920s.

A single-triode vacuum tube (01A, 37, or 76) is used as a very sensitive regenerative detector. This radio includes a set of plug-in tuning coils (550-1750kHz longwave and 29-47M shortwave), as well as sensitive antique headphones and required batteries. The set is constructed of the finest vintage fittings for that original 1920s look. It is easily operated from the front-panel controls, which include coarse- and fine-tuning dials, antenna-tuning dial, and regeneration control dial.

Any early radio enthusiast will be extremely pleased with the wonderful operation of this radio receiver when used with a good (easy-to-construct) antenna and ground system.

Kit available for $175. Kit comes with wound oscillating coils and assembled front panels. You do all the wiring and finish the hardwood base. To build this kit, you will need a soldering gun, solder, sandpaper, and wood finish. You will need to read electronic schematic diagrams, follow instructions and picture diagrams to lay out parts, follow a vacuum tube pin layout, solder, apply power to a filament and a B supply in proper polarity, and make a simple wire antenna and ground arrangements. Building and operating instructions are included.

I have really enjoyed using the Single Triode radio. And I really appreciate all your great work and assistance on learning about it.

I got the single regen set powered up over the weekend and it works great. Beautifully constructed; a really nice job.

Thanks, again, for making such a beautiful work of art. It really is fabulous!

Just a note to tell you I have completed the single regen radio. I am as much pleased by the set's eye pleasing elegance as I am with the stability and performance. The single 01A tube, vintage brand name tuning capacitors and hardware surpass the gain and selectivity of my modern solid state expensive receivers. The set is a joy and easy to operate and consumes very little battery power. Distant AM broadcast, foreign SW, CW, SSB amateurs—no problem. Thank you!
